To @ZZ whom t may concern:

Be it known that I, OTTO C. Onrinnn, a citizen of the United States, residing at St. Louis,.ldissoi`iri, have invented a certain new and useful improvement in Brick-Masons Tools, of which the following is a full, clear, and exact description, such as willenable others skilled in thev art to which it appertains to make and use the same. j

This invention relates to a tool that is adapted to be used .by a brick mason for raking` out the mortar joints of a brick structure, so as to prepare jointsfor tuckpointing ory for producing recessed joints.

One object of my invention is to provide a. tool of the character referred to that is equipped with an adjustable raking device `which can be adjusted easily to vary the depth of the raked joint. n

Another object is to provide a Acompact tool cf the character referred to that is inexpensive to manufacture and of such construction that the portions of saine which engage the brick during the raking; opera- Other objects and desirable features of my invention will be hereinafter pointed out. o

Figure l of the drawings is a longitudinal sectional view of a tool constructed in accordance with my invention, illustrating the method of using the tool to rakeout a horizontal mortar joint of ay brickstructure.

Figure 2 is an edge view of said tool. Figure 3 is a top plan view of the tool, illustrating how the smoothing portion on the handle of the tool is used to produce a recessed joint; and

Figure fi is a perspective view, illustrating` the method of using the tool.

Referring to the drawings` which illustrate the preferred form of my invention, A designates the handle of the tool` which is preferably of plate-like form` B designates a pair of arms that project forwardly from Said handle,` C designates 'a cross piece kor brace attached to the arms B intermediate the ends of same, and D designates a raking device adjustably mounted. on said cross piece C and provided with a head l that is located beyond the ends or terminal portions of the arms B. To use the tool to rake out the horizontal joint of a brick structure the operator grasps the handle A of the tool in one hand, then arranges the terminal ends of the arms B in engagement with the two courses of brick above and below the joint that is kto be raked, as shown in Fig urell, and thereafter drags the ltool longitudinally ofthe joint over the outerffaees of the courses of brick lying above fand be low the joint so as to cause the raking device D to remove some ofthe mortar from between said courses', and thus produce what is commonly referredto as a raked joint. lf the joint is to be tuck-pointed the raking device D is set so that the head l of saine is positioned a considerable distance beyond the terminal ends ofthe arms B, so as to produce a relatively deep joint.` If a re-r cessed joint is .to be formed the raking r device D is set so that thek head l of saine is positioned only a relatively slight distance beyond the terminal ends of the arms B. In producing a lrecessed joint it is necessary to smooth out the mortar of the joint after the 1ra-king operation, and in order that this ope ation may be performed with the same tool which is used to rakeout the joint, I provide the handle A of the tool with a smoothing portion Etliat is used kby turning the tool end for end, then introducing the smoothing portion E of saine into the rakedv joint, as shown in Figure 3, andthereafter moving the tool longitudinally of ythevjoint sous to cause the edge of the smoothing portion E to smooth down theinortar and make` it even. The arms B are preferably rprovid,-

' ed with enlarged terminalportions 2, and

in order to prevent saidy terminal portions from wearing out rapidly, I equip them with inserts 3 formed lfrom metal that has great wear resisting properties. Generally, `the handle A, the arms B and the cross piece C of the toolwill be constructed from a, castjoint. The raking'device D can be adjust j ably mounted on the tool in various ways without departing from the spirit of my invention, but I prefer to provide said raking device with an externally screw-threaded portion 4 that passes through an internally screw-threaded hole in the cross piece C and which carries a jam nut 5 that is used to lock said raking device in adjusted position, said jam nut being held against accidental movementby a spring lock washer G that is interposed between the jam nut 5 and the cross piece C into which the raking device is screwed.

A tool ot the construction above described makes it possible to produce uniform raked joints in a brick structure; it can be adjusted quickly and easily to produce shallow joints or deep joints; it can be used to prepare mortar joints for tuck-pointing or to produce recessed joints; 'it is compact enough and light enough to enable it to be carried conveniently in a brick masons pocket; it can be manufactured and sold at a low cost due to its simple design, and as the terminal portions of the arms B are provided with inserts of steel or other hard material7 long usage does not materially intertere with the operation of the tool.

Having thus described my invention, what I claim as new and desire to secure by Letn ters Patent is:

l. A brick masons tool, comprisinga handle provided with arms whose ends are adapted to be arranged in engagement with a brick structure at opposite sides ot a mortar joint in said structure, and an adjustable raking device positioned between said arms and projecting forwardly beyond the ends of same for removing some of the mortar from said joint when the tool is moved lengthwise of the joint.

2. A brick masons tool, comprising a handle provided with arms whose ends are adapted to be arranged in engagement with a brick structureat opposite sides of a mortar joint in said structure7 an adjustable raking device positioned between said arms and projecting forwardly beyond the ends of same for removing some of the mortar from said joint when the tool is moved lengthwise of the joint, and a portion on said tool that is adapted to be used to smooth down the mortar in the oint after the joint has been raked.

3. A brick masons tool, comprising a handle, a pair of spaced arm attached to said handle, large terminal portions on said arms provided with inserts formed o material that has great wear-resisting properties, and an adjustable joint raking device arranged between said arms.

4i. A brick masons tool consisting ot a cast metal handle provided at one edge with an integral smoothing portion and at its opposite edge with integral arms arranged in spaced relation, a cross piece or brace integrally attached to said arms intermediate the ends of same, a joint raking device provided with a screw-threaded portion that passes through a screw-threaded hole in said cross piece, and a jam nut arranged on said screw-threaded portion above said cross piece for holding saidvraking device in adj usted position.

5. A brick masons tool consisting ot a cast metal handle provided at one edge with an integral smoothing portion and at its opposite edge with integral arms arranged in spaced relation, a cross piece or brace integrally attached to said arms intermediate the ends of same, a joint raking device provided with a screw-threaded portion that passes through a screw-threaded hole in said cross piece, a jam nut arranged on said screw-threaded portion above said cross piece, a lock washer interposed between said jam nut and cross piece, and enlarged terminal portions on said arms provided with inserts formed by coiled steel springs that are imbedded in said terminal portions.
